A Study of Parameters Affecting Cutting Forces in Minimum Quantity Lubrication-Assisted Cross-Peripheral Grinding of Alumina Ceramic

Abstract

Ceramic materials have a widespread application in optical, biomedical, and aerospace field because of the high mechanical strength, excellent corrosion, and wear resistance. But due to the high hardness and low-fracture toughness of ceramics, it is a great challenge to make damage-free and precise ceramic parts with conventional methods of machining. Cross-peripheral grinding (CPG) is an advanced method of machining where a rotating hollow diamond core tool with diamond grits impregnated or electroplated at the lateral and end face of the bottom portion promotes grinding action for material removal. In this study, minimum quantity lubrication (MQL)-assisted CPG experiments are carried out to find the effect of process parameters on the cutting force. Box-Behnken design (BBD) was selected to generate the experimental runs. Analysis of variance is performed, and the significant parameters which affect cutting force are found out.
